I believe its $50 Then $30 and then $10 for the rest up to 25 lines.
(it used to be $80 for 2 $10 for the next 4 and then $20 for all lines after that but 2 months ago they dropped it to $10 for all the rest of the lines)
Wow, so I'm better off combining my 2 accounts into one business account. Although can you still get employee discounts on a business line? Even without the 15% though, seems like it would be cheaper to be a business account.
